Chemistry and Structure of Natural Rubbers | Rubber Chemistry

The question addressed in this paper is the chemical structure of the rubber in the plants—the micro-structure of the rubber, the molecular weight distribution, and the branching or gel content. Guayule natural rubber has the remarkable feature of containing no gel when taken directly from a fresh plant and carefully handled in the laboratory.

Natural Rubber: Structure and Function - Halcyon | The world

Natural rubber is a polymer, a long, chain like molecule that contains repeating subunits. The term polymer comes from the Greek “poly” meaning many and “mer” meaning parts. The chemical name for natural rubber is polyisoprene. The monomer (meaning “one-part”) from which it is built is isoprene. It is worth mentioning here that

Rubber. Rubber is an elastomer—that is, a polymer that has the ability to regain its original shape after being deformed. Rubber is also tough and resistant to weathering and chemical attack. Elastomers can be naturally occurring polymers, such as natural rubber, or they can be synthetically produced substances, such as butyl rubber, Thiokol

Chemical Structure of Vulcanized Rubber | Rubber Chemistry

The treatment of rubber to give these desired properties is known generally as vulcanization and must be considered as the basis for the enormous growth of the rubber industry and the extensive use of rubber products in our everyday life. Broadly speaking, vulcanization involves the reaction, in some fashion, of sulfur with rubber.

properties of synthetic rubber

Properties of Synthetic Rubber

The chemical structure of synthetic rubber adhesives is determined by two hard ends and a flixible middle part. Chemists would say: Styrene – Butadiene – Styrene or in short "SBS" The proportion of hard ends to the middle part determines how strong or firm the synthetic rubber is – and thus ultimately how mobile or soft the adhesive of

How is rubber Vulcanised? The chemistry and history

Natural Rubber chemical structure after vulcanisation. Isoprene molecular chains (CH3) are crosslinked by Sulphur (S). This crosslinking produces a netlike structure that gives a more stable elasticity than the purely electrostatic nature of the pre-vulcanisation bonds, and once created, this vulcanised material cannot easily be broken down.
